Grid software components

2. Management components

Any grid system has some management components.

1. First, there is a component that keeps track of the resources available to the grid and which users are members of the grid. This information is used primarily to decide where grid jobs should be assigned.
2. Second, there are measurement components that determine both the capacities of the nodes on the grid and their current utilization rate at any given time. This information is used to schedule jobs in the grid. Such information is also used to determine the health of the grid, alerting personnel to problems such as outages, congestion, or overcommitment. This information is also used to determine overall usage patterns and statistics, as well as to log and account for usage of grid resources.
3. Third, advanced grid management software can automatically manage many aspects of the grid. This is known as autonomic computing, or recovery oriented computing. This software would automatically recover from various kinds of grid failures and outages, finding alternative ways to get the workload processed.
